Airline Ryanair has said it will shut down its website and mobile app services for 10 hours this weekend.

The firm confirmed that its online check-in service will be unavailable from 7pm Irish time on Friday, June 19, to 5am Irish time on Saturday, June 20.

The company is rolling out a systems upgrade and called on customers travelling on those days to check in online for their flight on or before Thursday "well before the web closure takes place".

Ryanair added in a statement: "New bookings or changes to existing flights will not be possible during this web closure.

"Ryanair is contacting all intending customers travelling on Friday 19 and Saturday 20 June by email and SMS text to advise them to check in online on/before Thursday, 18 June to avoid this disruption.

"Ryanair apologises for any inconvenience caused by this web closure/systems upgrade."
